"Retail investors in the UK lost more than 197 million GBP to scammers in 2018 alone, the local Financial Conduct Authority (FCA) reports. The numbers, based on 6759 complaints and data form Action Fraud, the UK’s national fraud reporting service, mean that on average a scam victim has lost 29 000 GBP.

The most common scams were connected to offshore, unregulated companies offering forex trade, as well as cryoto currencies, stocks and bonds. Scams with those asset classes amount to 85% of all fraudulent activities in 2018."
